DRIVING MECHANISM FOR PAPER-BEFINING ENGINES.

Specification of Letters Patent.

Application filed October 18, 1909. Serial No. 523,177.

To all whom it may concern:

Be it. known that I, FRANK E. SAECKER, a citizen of the United States,and resident of Appleton, in the county of Outagamie and State ofWisconsin, have invented certain new and useful Improvements in DrivingMechanism for Paper-Refining Engines; and I do hereby declare that thefollowing is a full, clear, and exact. description thereof.

The object of my invention is to provide simple, economical andeffective means for coupling driving mechanisms to the plug shafts ofpaper refining engines, its construction and arrangement being such thatthe driving mechanism is longitudinally ad justed with relation to theplug shaft, lateral strain of the driving mechanism shaft beingeliminated owing to the factthat the power applied to move said drivingmechanism is eXerted upon the casing or frame of the same independent ofits shaft. The driving mechanism in this instance being shown as anelectric motor.

The invention therefore consists in certain peculiarities ofconstruction and combination of parts to be fully set forth hereinafterwith reference to the accompanying drawings and subsequently claimed.

In the drawings Figure 1 represents a side elevation of a paper refiningengine of the Jordan type and an electric motor for driving the sameprovided with attaching means to the refining engine shaft embodying thefeatures of my invention. Parts being broken away and parts in sectionmore clearly illustrate structural features. Fig. 2. a detail plan viewof the motor supporting base. Fig. 3. a transverse section of the sameas indicated by line 3-3 of Fig. 2, and Fig. 1, a detail cross-sectionof the motor coupling as indicated by line 4.t of Fig. 1.

Referring by numerals to the drawings, 1 indicates the shell of therefining engine supported upon a bed 2, and 3 the shaft of said engine,which shaft is suitably mounted in bearings 4 of the usual type. Theshaft is provided with a plug 5 having the usual cutting knives whichco-act with similar cutting knives carried by said plug. As is the casewith refining engines of this type, the shaft and plug arelongitudinally adjusted to insure proper relation between the stationaryshell knives and those carried by said plug. This adjustment is obtainedthrough an adjusting mechanism under the control of a hand-wheel 6,which handwheel is mounted upon a threaded adjusting spindle 7. The bedof the refining engine is provided with an extension base 8 securedthereto, which extension constitutes a motor base, and in some instancesthe latter may be formed in one piece with the engine base instead ofbeing an attachment as shown. The motor base 8, as shown in Fig. 2, isprovided with longitudinal troughs 9, which troughs form part of themotor base, there being a pair of separable intermediate troughs 10secured to the base as shown. Each of these troughs are provided withcross-partitions 11, which partitions divide the same into a series ofseparate cells into each of which is mounted a roller 12 provided with aperipheral V-shaped groove, the rollers being arranged to rotate in anoil bath contained in the cells as is shown in Fig. 1. Supported uponthe several series of rollers is a table 13, which table for conveniencein construction, is formed in halves being overlapped and centrallysecured together by bolts 14:. The lower face of the table is providedwith V-shaped longitudinal ribs 15, which ribs constitute rails adaptedto fit within the V-shaped grooves of the rollers. The longitudinalupper edges of the table are confined by strips 16, the strips beingsecured to the motor base and overlap said table edges.

The casing or frame 17 of an electric motor is secured to the table bybolts 18, the motor being provided with the usual shaft 19 revolublymounted in its casing or frame and arranged to have slight longitudinalplay in said bearings, which play is common to motors of this class andis provided for the purpose of insuring efficient results in itsoperation. The proportions of the motor casing or frame, are such thatwhen it is secured upon the table its shaft is in axial alinement withthe plug shaft 3 of the refining engine.

Secured to the end of the shaft 3 is a flanged collar 20, to whichcollar is bolted a flanged collar 21, the two collars constituting acoupling member between the motor shaft 19 and engine shaft 3. Theflanged collar 21 is sleeved upon the motor shaft 19 and in splinedconnection therewith, being provided with an external groove 22 for thereception of spanners 23, which spanners are bolted or otherwise securedto the motor casing or frame as shown in Fig. 1.

From the foregoing description it will be Patented Mar. 15, 1910.

seen that when the plug 5 is adjusted by means of the adjusting wheel 6,longitudinal movement of the plug shaft 3 will, through couplingconnection and spanner arm 23, cause the motor to move with said plugshaft and thus all strain incidental to the adjustment is taken off ofthe motor shaft, which is free to have its normal play. WVhen the motorcasing or frame is thus moved back or forth, the table 14 will have alongitudinal movement upon the rollers 9 and 10 due to engagement of therails 15 within the grooves of said rollers.

By utilizing a double set of rollers as described it will also be seenthat lateral play of the table is avoided, which table is held rigidlyto the rollers by means of strips 16, the friction of these parts beingthus reduced to a minimum and the V-shaped rollers, while permittingfree movement longitudinally, also prevent lateral movement withoutresorting to other rollers or anti-friction de vices for accomplishingthis result.

Heretofore paper refining engines have been driven by and connected toelectric motors, but in such instances the motor casing has either beenadjusted longitudinally by means independent of the plug adjustmentmechanism, or the motor and its shaft has either been fixed or directlyadjusted through power applied to the motor shaft the effect of whichwould cause undue strain on said motor shaft and a consequentdisplacement of the same relative to the fixed parts of said motor. Inmy present construction the motor is adjusted with the plug shaft, butsaid plug shaft exerts direct strain only upon the casing or frame andthus the objectionable features before mentioned are overcome.

WVhile I have shown an electric motor adjusted by my improved mechanism,it is obvious that said mechanism may be always applied to a pulley, inwhich instance the spanner arms 23 would be secured to the frame orshaft bearings of said pulley, which bearings would be the equivalent ofthe motor casing or frame 17.

In some instances in place of utilizing a two part coupler as shown inFig. 1, a single member may be connected to the plug shaft 3, in whichcase the member would be provided with an annular groove 22, the resultof such construction, it is apparent, would be the equivalent of thatshown.

I claim:

1. In a refining engine, the combination of a stationary shell, asupporting bed for the shell, a plug rotatively mounted within theshell, an endwise adjustable shaft on which the plug is supported, amotor casing adjustably mounted upon the refining engine bed, a motorrevoluble in the casing, the motor shaft being in axial alincment withthe plug shaft, a collar secured to said plug shaft, another collarsecured to the first named collar having a sleeve extending over themotor shaft, the sleeve being in splined connection with said motorshaft, an annular groove in the last named collar and spanner armssecured to the motor casin having ends engageable with the annulargroove of the aforesaid collar.

In a refining engine, the combination of a stationary shell, asupporting bed for the shell, a plug rotatively mounted within saidshell, an endwise adjustable shaft on which the plug is supported, a bedextension carried by the refining engine bed, longitudinal troughs inconnection with the bed extension, the troughs being provided with aseries of lateral partitions whereby separate cells are formed, V-shapedgroove rollers revolubly mounted in the trough cells, a table havingV-shapcd rails depending therefrom and engageable with the V-shapedrollers, guide strips secured to the bed extension and overlapping saidtable, a motor casing secured to the table, a motor shaft revoluble inbearings of the casing, a coupling secured to the plug shaft, a sleeveextension in connection with the coupling for engagement with the motorshaft, the motor shaft being in splined connection with said sleeve, anannular groove in the aforesaid sleeve, and spanner arms secured to themotor casing having ends engageable with the annular sleeve groove.

In testimony that I claim the foregoing I have hereunto set my hand atAppleton in the county of Outagamie and State of VVisconsin in thepresence of two witnesses.
